Firefox Community Forum

I have a local file I wish to view in firefox without starting a HTTP server (it's only docs for a crate I'm building) however Firefox is unable to open the file despite the file existing and having correct permissions. The file was in a separate mount (disk) to where Ffox is installed so I copied to to /tmp/ to remove that as a variable but still no joy..

➜ ~ file /tmp/index.html /tmp/index.html: HTML document, Unicode text, UTF-8 text, with very long lines (3556) ➜ ~ ls -la /tmp/index.html -rwxr-xr-x 1 ben ben 4208 Dec 30 14:04 /tmp/index.html

Am I missing some new setting which allows local file browsing using the good old 'file:///' protocol?

Thanks, Ben

[I am not sure this question is for Settings. None of the categories offered really seemed to fit this issue very well. Suggestions for re-posting are welcome.] On Firefox for Mac, Apple now has a pop up bubble to display the requested six digit 2FA number, first in the upper right corner, then, annoyingly, repeating often in multiple additional useless places on the screen, whether or not the code has already been used. The Apple community says there is no way to block this misbehavior through Apple, except disabling all 2FA, which is a bad idea. Is it possible to block the multiple appearances of 2fa code advisory bubble all over the place through Firefox controls? This problem reportedly does not appear on the native Mac Safari, nor reportedly on Chrome. I got to admit, I don't sign into Firefox, and not being forced to do so is a Firefox attraction for me. ]

Hello, I have tried everything...filters, added contact, blocked senders but I'm still not receiving any email from Firefox. I need my verification numbers to continue to sign into my account. thanks in advance for helping, Scott

I've been using Firefox for a while, and while there are many things I like about it, it has always been a resource hog. In the past I could get around this by just killing Firefox in Windows Resource Manager and restarting, but ever since getting a new computer an upgrading to Windows 11, it's gotten worse. Every couple of days my computer freezes for 10 or more minutes, I'm having to do a hard reboot ever few days, and I'm even bluescreening about twice a month. I'm pretty sure Firefox is the culprit because killing it will usually resolve the issue.

I'm wondering if there is some way to put Firefox in a sandbox so it does not consume nearly all available memory and other computer resources. It is by far the biggest consumer of resources on my system and I do not want to dedicate 4GB+ of memory to an app that is just showing a couple of web pages and playing YouTube videos.

I've been using what I gather is an "older" profiles system via about:profiles.

Now if I:

1. go to about:profiles and open my second profile in another window, 2. close second window and about:profiles page, 3. open about:profiles again in first window,

I get "Another copy of Firefox has made changes to profiles. You must restart Firefox before making more changes."

This happens every single time, even though I've made zero changes to profiles, and is extremely annoying.

Can/should I migrate my profiles to the new profile manager? How to do this?

I have tried endlessly to go onto Anesco website, it comes up with Forbidden 404 on all their sites, my solar system is managed by them but I cannot access the sites to contact them anyone got any ideas please, https://anesco.com/

What causes Firefox to freeze when two video windows are opened, i.e. in a new tab, the video windows immediately start to freeze? I use Windows 11. Other browsers work fine, only Firefox freezes with two windows open.

I'm getting announcements of a virus threat that purports to come from Mozilla Firefox. Usually one or all three of the attached small windows that say: 1. "Viruses Found. Antivirus notification. via https+++d512ucanaffc739fe48g.cgm-defender.pro" With a Dismiss button. 2. Attention! Click here to secure your data!. via https+++d512ucanaffc739fe48g.cgm-defender.pro" With a Dismiss button. 3. "System Warning!. Click here to remove them! via https+++d512ucanaffc739fe48g.cgm-defender.pro" With a Dismiss button. I have run full scans and offline scans with MS Defender, but these warnings still appear. Is this legit? I suspect these are a virus of some sort. Either way, how do I deal with this?

Greetings Ya'll,

I have to apologize if this is a double post, but I came back to the forum, & wanted to see if there were any responses, but i could only find my post listed under "My Profile"/"My Questions".

My original post was made Dec. 19-2025

=======================================

Early this morning as I went to use the Firefox browser, on My Desktop, I got an update, & then firefox opened, somewhat.

The homepage did not fill in with favorites, suggestions, etc, and in fact all that did load was the Search bar, but not one of my usual website buttons. The "edit", "help", etc. buttons at the upper left hand corner did load, but that is all. Not one of the buttons work, nor can I close out the Firefox page, by tapping the "X" in the upper right hand corner.

The only way that I could close out the "Firefox Page" was by going through the "Control/Alt/Delete" & then "Signing Out", which would initiate a "Re-start". Once I signed in, I could return to the Desktop, where everything works.

I use Firefox as my Browser on my Android phone, & at this moment, I've not had any problems using Firefox on my Cell Phone.

The only way that I could get to the Mozilla Website was by using the Microsoft Edge Browser, which is not giving me any problems as far as accessing the Internet!

How can I correct this problem, & go back to the Firefox Browser?

Once again, when I updated Firefox, it changed a LOT of my settings, including displaying the toolbar and open tabs bar.

When this happened last - months ago - it seems Mozilla realized this had happened to a lot of users, and managed to restore us to all the information that had been "lost".

I hope you can do that again, and can find a way to not put at least ME, and I'd bet a lot of other users, through the OMG!!! What do I do NOW?! panic.

Happy Holidays.

I have made multiple efforts to download Firefox onto a recently acquired laptop but it doesn't launch.

The laptop is a Dell Latitude 5520 running Windows 11 Pro.

I have on several occasions downloaded Firefox.exe (version 146.0.1.763), double clicked to start it, clicked to approve that the app can make changes and watched as the installation graphic fills and I get confirmation that installation has completed. Then nothing.

I have uninstalled the app and started again. No change.

The app appears in the list of apps (I have successfully made Firefox the default browser) but I don't know how to launch it.

I would be grateful if someone could provide the solution!

I want to drop ALL SPORTS CONTENT ON MY NEW PAGES & HOME PAGE. Every day I 'dismiss' every one. I 'thumbs down' every one. I've reported as SPAM, OUTDATED, tried to find modifications in 'settings'. I've clicked on the pencil at the bottom right corner...ZERO help. All I could find is the choice to "allow" or "not allow" recommended by & curated by staff. HELP ME MAKE IT STOP, PLEEZE.

I have a warning underneath my bookmark ribbon that says, "The security sandbox is disabled. Your configuration is unsupported and less secure." What is the security sandbox and what configuration is needed so that it supports the security sandbox. What happens if this security sandbox is disabled while I'm running Firefox?

I'm running Firefox v146.0.1

For awhile now I have trouble completing purchases on some websites when using Firefox. I need to open another browser like Edge to complete the transaction. Anything using "Shop with Visa" doesn't work and, for example, I just had to buy tickets on StubHub through a regular credit card submission. I bought them 4 times, got confirmation, and then had the order cancelled because it didn't go through. I called my credit card and was on with StubHub tech support. The final solution was to open Edge and make the purchase and it went through and I had the tickets a minute later. I'm now having the same issue trying to make a reservation at a restuarant through sevenrooms.com Its been sitting on the confirmation page for several minutes. I went into edge and made the reservation and it was confirmed with 30 seconds.
